PROBLEM TO BE SOLVED: To provide a steel sheet pile foundation structure capable of sufficiently exhibiting vertical bearing force of a longitudinal long size sheet pile and a side surface long size sheet pile for forming a tip processing part, by preventing yield deformation of the longitudinal long size sheet pile and the side surface long size sheet pile.SOLUTION: The present invention relates to a steel sheet pile foundation structure 1 for providing a plurality of steel sheet piles downward from a footing 21. The steel sheet pile foundation structure 1 comprises a longitudinal sheet pile group 3 and a side surface sheet pile group 4 provided on the footing 21. The longitudinal sheet pile group 3 is juxtaposed with a longitudinal long size sheet pile 31 erected up to the support ground 82 by installing a longitudinal reinforcement member 6 in a predetermined depth range and a longitudinal short size sheet pile 32 erected up to the weak ground 82. The side surface sheet pile group 4 is juxtaposed with the side surface long size sheet pile 41 erected up to the support ground 82 by installing a side surface reinforcement member 7 in a predetermined depth range (h) and a side surface short size sheet pile 42 erected up to the weak ground 82. |
